firewire: ohci: reorder struct fw_ohci for better cache efficiency
The config_rom struct members are only accessed during relatively infrequent self-ID-complete interrupts and only if the local config ROM was changed, while the ar_, at_, ir_, it_ members are used very frequently during I/O. Hence move the config_rom members further down. More importantly, make the huge self_id_buffer member the last one; this is only accessed in self-ID-complete interrupts.
